If the Mac Contacts are not synchronizing with iCloud

There are some situation in which the Contacts on the Mac are not updated with your iCloud contacts.

In this case, if after having done a logout-login your contacts are still not updated you can try the following procedure:

1. Close the Contacts app
2. From the Finder's Menu "Go To" select "Go to Folder..", or press CMD-SHIFT-G
3. In the Popup Window put the following String

   /Users/user_name/Library/Application Support

   and hit Enter or click on Open (*)
4. Inside the Folder "Application Support" search for a folder "AddressBook"
5. Now make a backup copy of this folder by dragging it while pressing ALT on the destination you want (you should notice a green icon with the symbol "+" inside).
6. Delete the folder
7. Start again the Contacts app

Now your contacts should be again synchronized with iCloud.

(*) Please note that "Users" can be in your system translated with your local language and that "user_name" should be changed with the username of the user where the problem is happening.

For the current user you can use the shortcout

~/Library/Application Support/AddressBook
